Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a catheterization device for urological patients. Background Technology

[0002] In the treatment and diagnosis of urinary system diseases, catheterization is an extremely common and important procedure. Due to the complexity of the urinary system, many conditions, such as urinary tract obstruction caused by benign prostatic hyperplasia, urinary dysfunction caused by neurogenic bladder, and the need for urine drainage before and after urinary system surgery, make catheterization a key means to solve patients' urination problems, monitor urine conditions, and ensure the normal physiological function of the urinary system. As the material basis for catheterization, the performance, design, and applicability of catheterization devices directly affect the effectiveness of catheterization, patient comfort, and subsequent recovery. From simple single-lumen catheters to more complex multi-lumen catheters, and then to catheters of various materials and coatings, as well as matching auxiliary devices, the emergence of each catheterization device is to better address the individual differences and clinical needs of different patients, playing an irreplaceable role in urological medical practice.

[0003] Currently, the catheters used for urological patients are usually of a specific diameter and generally do not have a fine-tuning function. However, in actual operation, it is sometimes necessary to adjust the catheter inserted into the urethra. However, after the catheter is inserted, the friction between the catheter wall and the urethra can easily cause discomfort to the patient, thereby affecting the patient's experience and treatment effect.

[0004] Therefore, this utility model provides a urinary catheterization device for urological patients to solve the above problems. Utility Model Content

[0007] Preferably, one end of the pipe is fixedly connected to a connector, and the inside of the pipe is connected to multiple interfaces of the connector. An air extraction valve is installed on the surface of the connector, and the air extraction valve can cooperate with an air extraction pump to perform air extraction operations.

[0008] Preferably, the interior of the tube is divided into four separate chambers by spacers, and the inner wall of the inner cavity is thinnest between the four independent chambers of the tube, and the air extraction valve is connected to the interior of the inner cavity.

[0011] Preferably, the positioning fluid bladder has a guide head integrally connected to the opposite end of the connector.

[0012] Preferably, the maximum radius of both the guide head and the initial positioning fluid bladder is smaller than the radius of the tube body.

[0013] Beneficial effects

[0014] This utility model provides a catheterization device for urological patients. Compared with the prior art, it has the following advantages:

[0015] Beneficial effects:

[0016] (1) This urological catheterization device, by setting a connector with an air extraction valve and a structure of four separate chambers separated by a cross-shaped spacer, allows the diameter of the tube to be finely adjusted and reduced during air extraction. In actual catheterization, after the catheter is inserted into the urethra, medical staff can use an air pump and an air extraction valve to extract air. The four chambers of the tube are concave inward under the pressure difference, and the diameter is finely adjusted by the pull of the spacer. Compared with traditional catheterization devices, this design reduces the friction between the catheter wall and the urethra by changing the diameter, improves the patient's experience, and is also conducive to the precise adjustment and positioning of the catheter in the urethra, thereby improving the treatment effect.

[0017] (2) This urological catheterization device, by setting an inner tube in the inner cavity and connecting the inner tube to the positioning fluid balloon through a hydraulic tube, will cause the inner tube to contract and deform due to the pressure difference when air is aspirated. The safety fluid inside will flow into the positioning fluid balloon through the hydraulic tube, causing the positioning fluid balloon to expand. The expanded positioning fluid balloon can effectively fix the catheter in the bladder and prevent the catheter from shifting or dislodging. Compared with traditional catheterization devices, expansion positioning and adjustment are carried out simultaneously, which is more convenient and faster. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 A urinary catheterization device for urological patients includes a catheter structure 1, which includes a tube body 11. One end of the tube body 11 is fixedly connected to a connector 12, and the interior of the tube body 11 is connected to multiple interfaces provided by the connector 12. An air extraction valve 121 is installed on the surface of the connector 12, and the air extraction valve 121 can cooperate with an air extraction pump to perform air extraction operations.

[0024] A cross-shaped spacer 111 is integrally connected inside the tube body 11, dividing the tube into four separate chambers. Each chamber is connected to an interface of a connector 12. An inner cavity 112 is formed along the path at the center of the spacer 111, and the wall of the inner cavity 112 is thinnest between the inner wall of the inner cavity 112 and the four independent chambers of the tube body 11. An air extraction valve 121 is connected to the inner cavity 112. An inner hose 113 is provided at the center of the inner cavity 112, and both ends of the inner hose 113 are fixed to the end walls at both ends of the inner cavity 112. The spacer 111 has a through hole at the opposite end of the inner hose 113 to the connector 12, through which the inner hose 113 passes. The inner hose 113 stores a safety liquid. The tube body 11 is connected to the connector 12. The two ends are integrally provided with a connecting pipe 13. The connecting pipe 13 is a tube platform structure, and several urine holes 131 are arranged in a ring array along the axis on its surface. A hydraulic pipe 132 is arranged at the axis position inside the connecting pipe 13, and one end of the hydraulic pipe 132 is fixed at the port of the channel opening at one end of the tube body 11 that communicates with the inner hose 113. The smaller radius end of the connecting pipe 13 is integrally provided with a positioning liquid bladder 14, and the interior of the positioning liquid bladder 14 is fixedly connected to one end of the hydraulic pipe 132 at the axis position of the connecting pipe 13. The positioning liquid bladder 14 is an inflatable liquid bladder and stores safety liquid inside. A guide head 15 is integrally connected to the opposite end of the positioning liquid bladder 14 that is connected to the connecting pipe 13. The maximum radius of both the guide head 15 and the initial positioning liquid bladder 14 is smaller than that of the tube body 11.

[0025] During operation, prepare and operate according to the operating procedures. When inserting the catheter, point the guide head 15 toward the urethra and use its smooth and small characteristics to push the catheter structure 1 into the urethra, reducing insertion damage. After insertion, use the air pump and air valve 121 to aspirate air. Aspiration reduces the pressure in the inner cavity 112, causing the four chambers of the tube body 11 to concave into the inner cavity 112. Under the pull of the spacer strip 111, the diameter of the tube body 11 is slightly reduced, making it easier to adjust and position the catheter in the urethra. At the same time, the inner tube 113 contracts and deforms due to the pressure difference, and the safety fluid inside flows into the positioning bladder 14 through the hydraulic tube 132 to expand it and fix the catheter. After the adjustment and positioning are completed, the urine is drained through the urine hole 131 of the adapter 13, the corresponding chambers of the tube body 11, and the corresponding interface of the connector 12.

[0026] In summary, by incorporating a connector 12 with an air extraction valve 121 and four separate chambers divided by a cross-shaped spacer 111, the diameter of the tube body 11 can be finely adjusted during air extraction. In actual catheterization, after the catheter is inserted into the urethra, medical staff can use an air pump in conjunction with the air extraction valve 121 to extract air. Under the pressure difference, the four chambers of the tube body 11 concave inwards towards the inner lumen 112, and the diameter is finely adjusted by the pull of the spacer 111. Compared to traditional catheterization devices, this design, by utilizing the ability to change the tube diameter, reduces friction between the catheter wall and the urethra, improving patient comfort. The improved experience also facilitates precise adjustment and positioning of the catheter within the urethra, thereby enhancing treatment effectiveness. By incorporating an inner flexible tube 113 within the inner cavity 112, and connecting the inner flexible tube 113 to the positioning balloon 14 via a hydraulic tube 132, the inner flexible tube 113 contracts and deforms due to the pressure difference during aspiration. The safety fluid inside flows into the positioning balloon 14 through the hydraulic tube 132, causing the balloon to expand. The expanded positioning balloon 14 effectively secures the catheter within the bladder, preventing displacement or dislodgement. Compared to traditional catheterization devices, expansion, positioning, and adjustment occur simultaneously, making it more convenient and faster.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] Working Principle: During operation, preparation and specific procedures are first followed according to the operating specifications. When inserting the catheter, the guide tip 15 is first oriented towards the urethra, and the catheter structure 1 is gradually pushed into the urethra using the guide tip 15. During this pushing process, the guide tip 15 is relatively smooth and small, which reduces damage to the urethra during insertion. After the catheter structure 1 is inserted into the appropriate position, the air pump and the air valve 121 are used to perform air aspiration. The air valve 121 is connected to the inner cavity 112. The wall of the inner cavity 112 is thinnest between the inner wall and the four independent chambers of the tube body 11. Air aspiration will reduce the pressure inside the inner cavity 112. With continuous air aspiration, the air pressure inside the inner cavity 112 gradually decreases. Under the action of pressure difference, the four chambers of the tube body 11 will push into the inner cavity 112. The inner tube 12 is concave, and under the pull of the spacer 111, the diameter of the tube body 11 is finely adjusted to be smaller, which facilitates further adjustment and positioning of the catheter in the urethra. At the same time, because the inner tube 113 stores safety fluid, under the action of pressure difference, the inner tube 113 will shrink and deform to a certain extent. As the inner tube 113 shrinks, the safety fluid inside will flow into the positioning fluid balloon 14 through the hydraulic tube 132, causing the positioning fluid balloon 14 to expand. The expanded positioning fluid balloon 14 can fix the catheter in the bladder and prevent the catheter from shifting or dislodging. After the adjustment and positioning are completed, medical staff can drain urine through the urine hole 131 on the surface of the adapter tube 13, which is in conjunction with the corresponding chamber in the tube body 11, and then through the corresponding interface of the connector 12.
